脉冲激光强化材料中冲击波的压强及其传播估算

Estimation of Shock Wave Pressure Intensity and Its Transfer During Pulse Laser Strengthening of the Material

本文对脉冲激光冲击强化后形成的冲击波的峰压及传播方式进行了讨论,得出其估算公式,为合理选择激光冲击强化的参数提供了参考依据,并给出了试验参数变化对冲击结果的影响规律。

In this paper, the peak pressure value of the shock wave is calculated and its propagation pattern formed after the pulsed laser shocking on metals is discussed. Several estimation for mulas are derived, which provide a basis for rational selection of the parameters of laser processing. The rules of variation of experiment parameter affecting on the results of shocking are also obtained.
